Do you sleep on your back, your stomach, or your side? A recent study by sleep expert Chris Idzikowski, director of the Sleep Assessment and Advisory Service, suggested a correlation between six common sleeping positions and the personality traits of the sleepers themselves. Preferred sleeping positions are seen as a sort of subconscious body language that reflects our inner traits. The study was commissioned by a large hotel group.
The most common sleeping positions (and corresponding personality) identified were:
Fetal Position (41%) Curled up on your side, holding the pillow. The most popular sleeping position, this one was favored by 51% of the women in the study. The personality of these sleepers tends to be shy and sensitive, though they may present a tough exterior to the world.
Soldier Position (8%) Flat on your back with arms at your sides. Indicates a quiet and reserved personality who sets high standards.
Starfish Position (5%) Lying on your back with arms and legs outstretched. Indicates a good listener who makes friends easily, but prefers not to be the center of attention.
Freefall Position (7%) Flat on your stomach with arms at the head or ears. Indicates a brash and gregarious exterior who may inwardly be nervous and sensitive to criticism.
Log Position (15%) On your side with legs outstretched and arms at your sides. Indicates a social, easygoing personality.
Yearner Position (13%) Similar to the log, but with arms outstretched. Said to indicate a suspicious and cynical personality.
Professor Idzikowski went on to say that the freefall position aided digestion, while the starfish and soldier sleeping positions were more likely to lead to snoring and an overall bad nights' sleep. But it may be as difficult to change as your personality itself; fewer than five percent of people slept in a different sleeping position every night.
Sleep and Who You Are
Freud called dreams the “royal road” to the unconscious—and at least as far back as biblical times, dream interpretation has been used in attempts to predict the future or discover hidden truths about our inner lives.
While modern research on sleep and dreaming makes smaller claims, it turns out that you can learn more than you’d expect about both health and personality by looking at various aspects of your sleep and dreaming life.
The Late-to-Bed, Late-to-Rise Sleeper
If you’re more productive, alive and energetic at night, you’re an owl. Your alarm clock—if you even have one—is likely buried under a pillow. Smolensky describes a classmate who would call wake-up services, set multiple alarms to ring and blast music, yet was still unable to get out of bed in the morning. Even though he forced himself to stay in when he had morning classes, he still couldn’t fall asleep early at night—and had to drop out of graduate school. Fortunately, most owls aren’t that extreme.
Owls are best left undisturbed before they've had their cup of coffee. In contrast to larks, low moods typically occur upon awakening, but mid-morning and late evenings are creative peaks.
“Owls seem to be more outgoing and social,” says Smolensky, “They also tend to be risk-takers.”
Teenagers are notorious owls—at puberty, the body clock changes and even those who tend to be lark-like become more nocturnal until their mid- to late 20s, when they revert to their more usual patterns.
Though most owls are able to adjust to the 9-5 work routine, extreme night owls may feel completely out of synch in such an environment. Consider a night shift, or a job you can do from home, on your own schedule.
The Long Sleeper
Another way in which our sleep styles vary involves how long we like to sleep. If you crave a lot of sleep—even more than eight hours per night—it's likely you fall into the category of “people who need people,” as the Streisand song goes.
Norah Vincent, Ph.D., an associate professor and clinical psychologist at the University of Manitoba in Canada, conducted a large study examining the relationship between sleep and personality in nearly 6,000 Americans.
"People who were more reliant on others for good feelings about themselves tend to sleep significantly longer,” she says, noting that there's nothing abnormal about this, it's just a measure on which people vary significantly.
However, long sleepers do have a tendency toward depression, a condition that is also very sensitive to the amount of social support people have in their lives. Staying in close touch with family and friends improves health for virtually everyone—but long sleepers should keep these ties strong and active.
The Necessity Sleeper
Are you the type who rarely sleeps eight hours? In fact, you can't imagine staying in bed that long? According to Vincent’s research, many individuals who sleep fewer than eight hours a day have a tendency to be highly self-critical. This could be because "you’re having harsh thoughts about yourself when you wake up during the night and when you attempt to fall asleep," she says.
Alternatively, the connection might be a result of being anxious in general. "You might tend to sleep shorter because you are in a chronic state of tension," she says.
Both over-sleeping and under-sleeping are associated with a higher than usual risk of death. No one has explained the connection with long sleep—but short sleep is known to increase blood pressure, which raises the risk for heart disease and stroke.
To improve short sleep linked with anxiety and self-criticism, Vincent suggests separating "worry time" and bedtime.
"We ask [patients] to schedule a time to have worrisome thoughts several hours before bedtime," she says. "It sounds very simplistic but even just the act of focusing on the thought makes it easier to defer having it." Patients tell themselves, 'This isn’t the time to deal with this, I’ll postpone it till tomorrow when I have set aside time to deal with these kinds of thoughts.'"
The Peaceful Sleeper
If you sleep like a log, you probably have an attitude of gratitude. A study of 161 people published in the Journal of Psychosomatic Research found that those who focus on what they have—not what they lack—fall asleep faster and sleep more soundly. Grateful people are also less tired and more functional during the day.
Why would being grateful affect your sleep? The researchers found that this was related to the thoughts people had as they drifted off. Being thankful led to faster, deeper sleep.
“People who are feeling more grateful are less tense and anxious, because the two are incompatible,” says Vincent. “A mental state like that at bedtime would be helpful for your sleep.”
The Restless Sleeper
If you find yourself counting sheep, watching late-night TV, swinging from branch to branch in your thoughts, or working into the night because you can’t sleep, consider your need for perfection or control.
While a perfectionist may be successful in many situations, this trait isn’t useful in the realm of sleep and relaxation. A controlling nature may also set the stage for long struggles when it comes to difficulties sleeping.
“We found that certain aspects of perfectionism are elevated in people with chronic insomnia,” says Vincent. “People who expect a lot of themselves and who don’t meet their own personal standards are more likely to have insomnia.” A perfectionist approach to sleeping itself—like an exaggerated sense of one’s ability to control things—can cause problems.
"If you believe that you are responsible for most outcomes and then you don’t have success in one area, there is a tendency to engage in self-blame and self-deprecation," says Vincent. This produces greater anxiety, which makes it even harder to fall asleep.
To break the cycle, recognize that there are only some aspects of your sleep environment that you can control. “We use a cognitive-behavioral approach and talk about what parts of sleep are controllable,” says Vincent, “You can’t control when you get sleepy but you can control whether you have a lot of coffee in the evening and the amount of light in the bedroom.”
If you struggle with insomnia, begin with recognizing your limits and accepting them as a normal part of life. Focus on the positives of your day as you prepare for bed, and you may find that sleep comes easier.
The Dreaming Sleeper
Can you vividly recall your dreams each morning? Your sleep style indicates that you are likely highly creative in your waking life.
"People with an intensely high level of dream recall have something called 'thin borders,'" says James Pagel, M.D., director of the Sleepworks Laboratory in Colorado Springs, Colo. "That means that for them, everything is in shades of gray, there's not whole lot of black or white. They’re not purely Democrats or Republicans; they are not quite asleep or awake; and they define much of their lives in that way."
Such people tend to be odd and quirky—and although most are perfectly normal, they are at higher risk than others for schizophrenia.
The Dreamless Sleeper
Until recently, it was widely accepted that all people dream—except, perhaps those with certain brain injuries. However, researchers have discovered that there are some people who appear to have no dreams at all—or at least, they never remember any. While you may worry that something is wrong with your memory, research indicates there’s no connection.
“Nine percent of people will say they don’t have dreams,” says Pagel. “When we specifically question them, 'Do you really not dream?'” most will say, 'Well, my last dream was years ago,' but a small number of people—2 in 1,000—say they have never ever dreamed.”
Pagel compared a group of non-dreamers to rare dreamers in a sleep lab, waking them up during various stages of sleep. About 10 percent of the rare dreamers did report having at least one dream—but the others did not.
“One was a math professor,” says Pagel. “Most of them had jobs and were very functional. There was nothing wrong with their memory, no abnormalities.”
So, if you don’t dream, don’t worry. It’s not known if people who never remember dreaming truly don’t dream, or just can never remember any elements of dreams—but it doesn’t seem to be a problem.
